[R] RODBC vs gdata

[Christof Kluß]

Hi

one col in my Excel file contains many numbers. But on line 3000 and
some other lines are strings like "FG 1". "RODBS" seems to omit this
lines. "gdata" works, but is much slower.

Is this a bug of RODBC or do I apply it wrong?

Example with the same "file.xlsx"


library(RODBC); excel <- odbcConnectExcel2007("file.xlsx")
tab <- sqlQuery(excel, 'select * from "Table 1$"'); str(tab)

col1: num  1 2 3 4 5 6 7 8 9 10 ...

library(gdata); tab <- read.xls("file.xlsx", sheet=1); str(tab)

col1: Factor w/ 51 levels "1","10","11",..: 1 12 23 34 41 42 43...


greeting
Christof
